Describe a real-life multiplication situation for which an estimate makes sense . Explain why it makes sense

monitta

Answer: Here we have a real life multiplication situation for which an estimate make sense:-

Miley has 212 fiction books. Sharon has 3 times fiction books has many as Miley has, how many fiction books Sharon has

Solution :- Number of fiction books Miley has = 212

Number of fiction books Sharon has= 3 times 212

We know that 212 is near to 200 , so round off 212 to 200 (to the nearest hundred)

Thus the product becomes $3\times200=600$

Therefore, the estimated number of fiction books Sharon has=600

Find the length of the median and the missing base. Be sure to show all your work. NO LINKS!!!

dezoksy [38]

Answer:

The bottom is 11

The median is 12

Step-by-step explanation:

The median is the average of the top and bottom

(13+ 2x-3) /2 = 4x-16

Combine like terms

(10+2x)/2 = 4x-16

Divide by 2

5+x = 4x-16

Subtract x from each side

5+x-x = 4x-16-x

5 = 3x-16

Add 16 to each side

5+16 = 3x-16+16

21 = 3x

Divide by 3

21/3 = 3x/3

7 =x

The bottom is 2x-3 = 2*7-3 = 14-3 = 11

The median is 4x-16 = 4*7-16 = 28 -16 = 12
